*''Chinese/Japanese'': 易經 ''(Yìjīng / eki kyou)''

The ''Yìjīng'', often known as the ''I Ching'' or the ''Book of Changes'' in English, is the most ancient Chinese text discussing [[yin and yang|''yin'' and ''yang'']], and the nature of the cosmos.

Believed to be a divination text from some much earlier period, its author and date unknown, the ''Yìjīng'' was taken up in the [[Han Dynasty]] as thinkers attempted to create a more coherent, complete, account of the fundamental nature of the universe.

The core of the text consists of 64 hexagrams, each comprised of a pairing of two of eight possible trigrams. The trigrams consist simply of a set of three broken or unbroken lines, with eight possible combinations (e.g. two unbroken and the third broken, or one broken and the second and third unbroken, etc.). Each broken line corresponds to ''yin'', and an unbroken line to ''yang''; thus, six unbroken lines represent Heaven, which is comprised purely of ''yang'', six broken lines represent the Earth, which is comprised only of ''yin'', and all other combinations represent all the multifarious things in between. Each of the sixty-four hexagrams is accompanied by a commentary.

Combined with concepts of the [[five elements]] (fire, wood, earth, metal, and water), the ''Yìjīng'' thus serves as the foundation for a conception of the universe as based in ''yin'' and ''yang'', articulated by scholars of the Han Dynasty. Later figures such as the [[Song Dynasty]] thinker [[Zhu Xi]] would expand upon this, to articulate a universe comprised of ''[[qi]]'', according to the universal principle ''[[li (principle)]]''.
